SAN DIEGO -- A closed-circuit UCSD television station broadcast apparent sex acts earlier this month, prompting an internal investigation aimed at determining if the show violated regulations, it was reported Saturday.

A 90-minute show called "Koala TV," which has aired three times this month, contains a 10-minute segment showing UCSD senior Steve York and unidentified woman performing sex acts, The San Diego Union-Tribune reported.

The show is a spinoff of The Koala, a satirical magazine distributed on campus that has printed irreverent and controversial material.

Contacted by the Union-Tribune earlier this week, York said he would agree to an interview only if the newspaper bought booze for him, the newspaper reported.

York told the UCSD Guardian newspaper that he wanted to "bridge the gap between students and their sexual desires in a fun way."

UCSD officials are trying to determine if the broadcast violated Federal Communications Commission regulations, the charter for SRTV, or any campus policies and procedures.

The probe, begun Feb. 11, is expected to take a couple of weeks, said Carmen Vazquez, assistant vice chancellor for student life.
